Pros & Cons

Prime Doctor RX

What we like

  • Every plan is priced on the homepage before you start, with month-to-month and 12-, 24- and 52-week prepaid rates for each drug
  • Names its prescribing medical group, OpenLoop Healthcare Partners, PC
  • Offers compounded semaglutide and tirzepatide injections plus a daily oral semaglutide tablet
  • States the real billing cycle plainly: month-to-month plans are charged every 4 weeks
  • Month-to-month plans can be canceled at any time, and refunds can be requested for unused future periods
  • Also runs testosterone and enclomiphene programs for eligible men, with the hormone-care state list published

Watch-outs

  • The '$179/mo' headline is the 52-week prepay average, paid as one $2,327 charge; month-to-month semaglutide is $249
  • Plans are charged every 4 weeks, so month-to-month billing comes to 13 charges a year, not 12
  • Ending a prepaid plan early can reprice the months you used at the higher month-to-month rate
  • No dispensing pharmacy is named anywhere on the site
  • No LegitScript certification, and no Trustpilot profile or other third-party reviews could be found
  • Weight-loss availability by state is not published; it is confirmed during intake
  • No phone number is published on the site; support is by email and an on-site chat widget
  • Product cards never say compounded or brand-name; only a footnote says compounded medications are not FDA-approved

CoreAge Rx

What we like

  • LegitScript certified — rigorous pharmacy standards
  • Free 2-day shipping nationwide
  • Both semaglutide and tirzepatide available
  • Lowest per-month pricing in the compounded segment
  • 24/7 support team
  • All 50 states covered

Watch-outs

  • Compounded only — no brand-name Ozempic or Wegovy
  • Newer brand with fewer independent reviews than legacy players
